Pros

The culture is super supportive and everyone is so nice! Most people genuinely care about the product and what they are working on. Many projects are bottom up instead of top down, it's a great place to learn and grow.

Cons

Being too nice could cause indirect communication and lacking of constructive feedback.

Pros

I have never seen a company so dedicated to its values. I know, I know, every company has a list of values and principles and claims to live by them blah, blah. But at Slack, it isn’t really any list of values, so much as it is an implied way of being. If you are collaborative, respectful, put team first, find creative solutions, the. You will be more successful here. In some cultures, that simply isn’t true - over time you get sucked into the grimy, political necessities. I have seen it, fallen victim to it, and I am never going back. Working at Slack, I feel liberated to to my best work. Stuart is amazing. The hype is real. Finally, I work in Sales, which is often the most competitive dog-eat-dog side of a company. Not here. We win together or we don’t win at all. I know it sounds crazy, but come see for yourself.

Cons

Typical growth challenges. We use Slack for EVERYTHING at work and once in a while, there is a better way to get something done.
